Topological control of third-harmonic generation in a mesoscopic quantum ring with spiral dislocation

Carlos Magno O. Pereira, Denise Assafrão, Edilberto O. Silva

We investigate the nonlinear optical response of a two-dimensional mesoscopic quantum ring subjected to a spiral dislocation, with emphasis on third-harmonic generation (THG). The…

Single-Scale Magnetoelastic Landau Quantization: Thermodynamics, Quantum Oscillations, and Metrology

Denise Assafrão, Faizuddin Ahmed, Edilberto O. Silva

We develop a unified, single-scale description of thermodynamics and quantum oscillations in electronic systems with a uniform areal density of screw dislocations under a uniform m…

Rotating effects on the Hall conductivity in a quantum dot

Carlos Magno O. Pereira, Luís Fernando C. Pereira, Denise Assafrão +1

We investigate the behavior of the quantized Hall conductivity in a two-dimensional quantum system under rotating effects, a uniform magnetic field, and an Aharonov-Bohm (AB) flux…

Modifications in the photoionization cross-section of a quantum dot with position-dependent effective mass

Carlos Magno O. Pereira, Denise Assafrão, Frankbelson dos S. Azevedo +3

In this work, we investigate the photoionization cross-section of an electron confined in a quantum dot, considering the position-dependent variation of the effective mass through…

Nonlinear refractive index changes and absorption coefficients in mesoscopic ring induced by variable effective mass

Denise Assafrao, A. G. de Lima, Edilberto O. Silva +1

This study explores the linear and nonlinear optical absorption coefficients (OAC) and refractive index changes (RIC) in quantum dot and quantum antidot systems with a position-dep…

Effects of quantum deformation on the integer quantum Hall effect

Fabiano M. Andrade, Edilberto O. Silva, Denise Assafrão +1

In this work an application of the --deformed algebra in condensed matter physics is presented. Starting by the --deformed Dirac equation we study the relativistic generaliza…
